Vue 2.5.1: Invalid value for option "components": expected an Object, but got Array.

After upgrading to Vue 2.5.1 I receive the following console warning:

Triggered by bootstrap-vue.esm.js:

        // Register components
        for (var component in components) {
            Vue.component(component, components[component]);
        }

Until fix is released, I worked around it using:

let originalVueComponent = Vue.component
Vue.component = function(name, definition) {
  if (name === 'bFormCheckboxGroup' || name === 'bCheckboxGroup' ||
      name === 'bCheckGroup' || name === 'bFormRadioGroup') {
    definition.components = {bFormCheckbox: definition.components[0]}
  }
  originalVueComponent.apply(this, [name, definition])
}
Vue.use(BootstrapVue)
Vue.component = originalVueComponent

putting together @kriomant and @Flygenring code, here is a complete workaround for Node, works for me on the entire bootstrap-vue import:

let originalVueComponent = Vue.component
Vue.component = function (name, definition) {
  if (Array.isArray(definition.components) && definition.components.length === 1) {
    definition.components = {[name]: definition.components[0]}
  }
  originalVueComponent.apply(this, [name, definition])
}

Vue.use(BootstrapVue)
Vue.component = originalVueComponent
